Docker私有镜像仓库Harbor
Harbor介绍
Harbor 是为企业用户设计的开源镜像仓库项目，包括了权限管理(RBAC)、LDAP、审计、安全漏洞扫描、镜像验真、管理界面、自我注册、HA等企业必需的功能，同时针对中国用户的特点，设计镜像复制和中文支持等功能。

Harbor安装部署
可以准备台新的虚拟机：docker02 10.0.0.200 2核4G
# 1.harbor安装的环境要求
安装Harbor必须有docker环境和docker-compose环境
yum install -y docker-ce
yum install -y docker-compose
# 2.解压harbor安装包
[root@docker02 ~]# tar xf harbor-offline-installer-v1.9.0-rc1.tgz
[root@docker02 ~/harbor]# ll
total 605144
-rw-r--r-- 1 root root 619632806 Sep 4 2019 harbor.v1.9.0.tar.gz
-rw-r--r-- 1 root root 5805 Sep 4 2019 harbor.yml
-rwxr-xr-x 1 root root 5088 Sep 4 2019 install.sh
-rw-r--r-- 1 root root 11347 Sep 4 2019 LICENSE
-rwxr-xr-x 1 root root 1748 Sep 4 2019 prepare
# harbor.yml //docker-compose的编排文件，有点像tower的Playbook
# 3.修改harbor配置
[root@docker02 ~/harbor]# vim harbor.yml
hostname: 10.0.0.200
harbor_admin_password: Harbor12345
# 4.执行安装脚本
[root@docker02 ~/harbor]# sh install.sh
[Step 1]: loading Harbor images ...
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
# 5.没启Docker，启下docker
[root@docker02 ~/harbor]# systemctl start docker
[root@docker02 ~/harbor]# sh install.sh
[Step 0]: checking installation environment ...
Note: docker version: 24.0.7
Note: docker-compose version: 1.18.0

Harbor的使用
harbor新建项目
新建一个h5_games项目，在里面可以看到相关推送镜像的命令。
在harbor中上传镜像
例：将上节docker01机器构建的镜像上传至harbor
# 1.修改镜像名称
# 查看镜像
[root@docker01 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx c7_v3 b61e011c7a89 28 hours ago 289MB
# 给镜像改名（会生成一个新的镜像，与原镜像同一个ID，是一样的。原来的可以删掉）
[root@docker01 ~]# docker tag nginx:c7_v3 10.0.0.200/h5_games/nginx:c7_v3
[root@docker01 ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
10.0.0.200/h5_games/nginx c7_v3 88b3d5a6d73f 2 hours ago 289MB

###命名规则###
照着上面截图命名即可：
harbor服务器地址/项目名称/镜像名称:标签
10.0.0.200/h5_games/nginx:c7_v3
# 2.修改docker配置文件，信任harbor仓库地址
[root@docker01 /etc/docker]# vim daemon.json
{
"bip": "192.168.10.1/24",
"registry-mirrors": ["https://pgz00k39.mirror.aliyuncs.com"],
"insecure-registries": ["http://10.0.0.200"]
}
[root@docker01 ~]# systemctl restart docker
# 3.登录harbor
[root@docker01 ~]# docker login 10.0.0.200
Username: admin
Password:
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
# 4.推送镜像
[root@docker01 ~]# docker push 10.0.0.200/h5_games/nginx:c7_v3
The push refers to repository [10.0.0.200/h5_games/nginx]
cc5163efebe5: Pushed
dff3e2c393d5: Pushed
174f56854903: Pushed

ps：每一层都有ID，其中有一个就是centos:7的层
刷新查看：
拉取镜像到harbor本机
# 直接拉报错
